摘要
采用热动力学的方法建立连续激光消熔单晶硅太阳电池的理论模型,计算简化模型温度场分布的解析解。根据实际中激光消熔单晶硅模型的高度非线性化,使用优化网格步长的Matlab程序,采用有限差分方法,在合适的时间内计算模拟了过程中非稳态温度场的分布以及消熔深度、消熔宽度和消熔形貌,得到的模拟结果与实验观测相吻合。
The theoretical model of continuous laser ablation of monocrystalline silicon solar cells using thermody- namic method was established and analytical solution by calculating the temperature field distribution of a simplified model was obtained. According to the highly nonlinear of model of laser ablating monocrystalline silicon, the un- steady temperature field distribution and ablation depth, ablation width as well as ablation morphology were simula- ted using the finite difference method in Matlab within appropriate time. The simulation results are consistent with the experimental observations.
